I sewed a long horizonal seam putting blocks together today. When I inspected it to see if all the corners were good, I found two burgandy triangles side by side. Was it the end of the world? Would anyone know but me? Maybe my oldest daughter, but it's not for her? Could I ignore it and leave it? NO! So out came the seam ripper. The whole 17" center block had to come out and be flipped. It's out now. Please don't let me put it back in the same way. I've done that with small errors. This is my largest error, what's yours?
